Background: Biomarkers specificity is an important factor for their reliable utilization. Known markers for acute myocardial infarction (AMI) including creatine kinase (CK) activity, C-reactive protein (CRP) level and blood cell counts are thought to be altered in other pathological conditions such as infections. Methods: We recruited 15 AMI patients, 15 patients with bacterial infections (infected control group) and 35 normal Subjects. Peripheral blood samples were obtained for blood cell counts and biochemical analyses. Results: We therefore compared these biomarkers in 15 AMI patients (troponin criteria > 0.100 ng/mL) and 15 infected controls with respect to 35 normal subjects. Only monocytes were significantly increased in AMI patients (0.793*109/L) than normal controls (0.497*109/L). Infected controls showed a significant increase in total WBC (11.50*109/L versus 6.149*109/L) and neutrophils (9.360 versus 3.223*109/L) counts and significant decrease in RBC (3.750 versus 5.105*1012/L) counts as compared to normal controls. Serum CK activity was significantly increased in AMI patients (313.20 ? 94.84 U/L) and decreased in infected controls (48.40 ? 10.35 U/L) as compared to normal controls (100.82 ? 8.86 U/L). The levels of CRP were significantly higher in infected controls (136.93 ? 34.83 mg/L) and non-significantly higher in AMI patients (38.53 ? 12.76 mg/L) than normal controls (3.48 ? 0.59 mg/L). Monocytes were significantly correlated with both CK activity and CRP level, however there was no correlation between CK activity and CRP level. Conclusion: Differential trends of monocytes and CK activity in AMI and infective controls point towards their possible application in prognosis of AMI patients.
